Flash Mob America and over 300 In the Heights fans surprised Lin-Manuel Miranda with an outdoor performance of “96,000” — from Miranda’s In the Heights — in Los Angeles, to celebrate Tony winner Miranda’s returning to the show he wrote and originally starred in for the tour’s L.A. stop at the Pantages Theatre.

In the Heights, the 2008 Tony Award winner for Best Musical, earned Miranda a Tony for his score and a nomination for playing charming bodega owner Usnavi. The tour plays the Pantages Theatre through July 25.
